I personally favor Warren Buffett's perspective a little more, however I'm not totally disregarding Musk perspective. I believe both are necessary for the success of Steemit. I requires vastly more energy and resources to maintain a fast pace for innovation, and far more difficult to maintain it. It is easy to maintain a moat once you've established one. Take Coke for an example. they maintain the same formula and spend far less on R and D than someone maintaining a fast pace for innovation. I do however believe that you do at some point need both.
